Genes affected
NPRL2 (HGNC:24969): (NPR2 like, GATOR1 complex subunit) Enables protein kinase activity. Contributes to GTPase activator activity. Involved in cellular response to amino acid starvation; negative regulation of TOR signaling; and negative regulation of kinase activity. Located in lysosomal membrane. Part of GATOR1 complex. Implicated in focal epilepsy. [provided by Alliance of Genome Resources, Apr 2022]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 20, 2023The c.1027C>T (p.R343W) alteration is located in exon 10 (coding exon 10) of the NPRL2 gene. This alteration results from a C to T substitution at nucleotide position 1027, causing the arginine (R) at amino acid position 343 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
